Print Head Deep Cleaning

After print head cleaning finishes
After print head deep cleaning finishes, print the nozzle check pattern to
verify that the print head nozzles are clean. See "Printing the Nozzle
Check Pattern" on page 39.
When one of the ink tanks does not print, see "Replacing Ink Tanks" on
page 36.
If the problem remains, make sure that ink remains in the ink tank, turn
off the printer's power for at least 24 hours, and then perform deep
cleaning of the print head again.
If the problem still remains, the print head may be damaged. Contact
the Customer Care Center.
